The hot water tank is no longer draining

Maintenance, cleaning or replacing the plumbing... Certain circumstances require you to empty your hot water tank.But does your hot water tank refuse to drain and you can't understand why? In this article, we'll explain the factors that may cause this problem.

THE POTENTIAL CAUSES FOR THIS FAULT:

• The water heater has too much limescale

• Limestone accumulation in the pipes

• Hot water tank is too worn out

WARNING
Before carrying out any work on your appliance, make sure you properly disconnect it from the mains electricity supply.
There is a risk of an electric shock.

The water heater has too much limescale

A regular discharge (approximately once a year) increases the life of your hot water tank. But that’s not all! It helps to descale it and prevent more serious problems. Attention: this descaling operation involves removing seals to access the tank, so you are advised to replace them in order to ensure the heater is properly watertight again. If you haven't flushed your hot water tank as often as you should have, limescale may prevent water flow and therefore will prevent you draining it. In order to prevent limescale building up in a hot water tank, you can install a water softener that extends the life of your device.

Purchase a heating element for a boiler

Limestone accumulation in the pipes

If the water in your home is naturally hard, limestone will tend to build up and even clog the pipes, preventing water from flowing properly. As above, the only option for avoiding this is to invest in a water softener.

Hot water tank is too worn out

Your hot water heater may be too damaged by limescale or rust, preventing optimal use of your device (meaning you can no longer drain it). If you see traces of rust or water coming out of your water heater, you may need to replace it.
